If the values in the following registry keys does not match the device information seen by the SCSI controller card, then Backup Exec 8.x will not use the autoloader device:

HKEY_Local_MachineOn Local MachineSystemCurrentControlSetControlSCSIChanger

HKEY_Local_Machine On Local MachineSystemCurrentControlSetServicesSCSIChanger

Un-installing and re-installing the backup software will not solve the issue. During the un-install process, BackupExec does not remove the registry keys mentioned above. During the re-install process, if the keys are detected, they are not re-written. If the keys do not match, then BackupExec will assume there is a hardware error, and will not display the device under the Devices tab.
